The current one is just a smaller version of the 12-man setup we normally play. Which is great, except for the roles that don't translate well to 6-man. Things like terrorist, invisible man, and amnesiac all suck in 6-man. They're just not fun. Cop sanity is also annoying, because there's not really enough time to determine your sanity accurately.

Lemme know if I messed up making it somehow, because I do that a lot.
